A fuzzy overlapping community is an important kind of overlapping community in which each node belongs to each community to different extents. It exists in many real networks but how to identify a fuzzy overlapping community is still a challenging task. In this work, the concept of local random...

In recent studies of the complex network, most of the community detection methods only consider the network topological structure without background information. This leads to a relatively low accuracy. In this paper, a novel semi-supervised community detection algorithm is proposed based on the...

For a user who is unfamiliar with a target domain, the first step to conduct an exploratory search task is to go over a learning phrase, which means to learn from the search results to acquire basic domain knowledge. Since lots of search results could be returned by a search engine, and usually...
